FIELD OF THE INVENTION

The present invention relates to a safe, eco-friendly, health protective and cosmetic composition useful as lipstick and for other cosmaceutical applications like eye-shadows, skin creams, glow-glitters and rouges.

BACKGROUND AND PRIOR ART

There is worldwide revival of interest in the use of natural colours especially in cosmetics and pharmaceuticals as the synthetic colours are likely to cause many side effects. Keeping this in view the present invention is undertaken to develop purely natural herbal colorants for cosmetic compositions. One aspect of the invention pertains to the development of a herbal composition useful as Lipstick with mood altering functional attributes including stimulation of creative thoughts on persons who apply the same on lips. Such features of the composition are attributed to the selected blended formulations of Natural colours and essential oils/aroma isolates incorporated.

Lips being the most sensitive part of skin, can effect fast transdermal absorption and also the lips being very close to nose facilitate a continuous inhalation of the slowly vaporizing essential oils/aroma chemicals blended in the composition, thus, providing a double effect on the specific centers of the brain by releasing neurochemicals leading to mood alteration stimulation and change of mental perceptions The different blends of essential oil/aroma isolates/natural aroma chemical selectively blended in the lipsticks provide anti-depressant, mood enhancing/mood lifting effect and give rise to creative thoughts.

While lipsticks with different colour shades blended with aromatic principles have been developed for women, another range of compositions useful as lipsticks has also been developed for men. These compositions are without colours but provide a moisturizing transparent effect and have mood altering functions and are designed to altered mental perception, functioning similar to the lipstick compositions developed for developed for women. Both the groups of lipstick have some additional health promotive/protective and beautifying attributes by preventing the lips from darkening and providing it with moisturizing effects. These compositions also give attractive luster and texture to the lips. The lipsticks with colour, developed for women, have antibacterial, antifungal and anti-inflammatory effects. With regard to lip beautification topical application lipstick with different shades of colours are well known. Likewise, spraying of aromatic oils or sprays for refreshing is also well known. Many studies have been carried out on the effect of fragrance on mental perception; for example, the nice fragrance has an aesthetic impression and multiple positive effects on our life, they are not only for pleasure and seduction, healing and magic products but also for positive mood creators.

DESCRIPTION OF PRIOR ART

Reference is made to a publication titled “Naphthaquinones of Arnebia Nobilis” by Y. N. Shukla et al., Phytochemistry, 1971, Vol.10, pp.1909 to 1915, wherein, 4-naphthaquinones designated as A-1, A-2,A-3 and A-4 have been reported. The use of the extract from Arnebia nobilis is also reported. Sayyada Khatoon and Shanta Mehrotra in “Naphtha quinones from some Boraginaceous Texa-A Chemical Review” published in Natural Product Sciences, 1996 2(2) pp.75-95 report a number of naphthaquinones from boraginaceous plants. Varies properties of these compounds have also been reported.

V. P. Papageorgiou, has reported certain lipophilic red pigments obtained from various plants including the genus Lithospermum, Echium Onosma Anchusa and Cynoglossum, in his publication titled: Naturally occurring Isohexenylnaphthazarin Pigments: A New Class of Drugs” in Planta Medica, 1980, Vol.38, No.3.

U.S. Pat. No. 4,996,044 describes a lipstick formulation consisting of organic high staining dyes, said formulation having creamy, shiny and soft laydown and long wear properties. The formulation does not use any extracts from any plant.

Reference is made to a U.S. Pat. (No. 5,593,662) wherein moisturizing lipstick has been described. In this invention, use has been made with a composition of 30-80% lipophilic material, which may have lesser shelf life and may promote microbial growth due to the presence of moisture. They used about 0-35% synthetic colourant which seems to he too high for a cosmetic composition. The synthetic colours mostly exhibit harmful side effects like loss of luster, blackening of skin and may have some carcinogenic effects too as shown in a website (http ://www.orst.edu/foodresource/color/colorants/.html).

Another reference is made to U.S. Pat. No. 5,665,778 wherein a ceramide, process for their preparation and their application in cosmetics and in dermato-pharmacy. These compounds are complex mixtures of erythro & threo-diasterioisomers. They synthesize these compounds by a complex and costly process. They have used organic pigments for lipstick and there is no herbal colourants being used.

Reference may be made to a recent PCT application PCT/EP00/02217 of 13 Mar. 2000 wherein the inventors have used Zinc salts, particularly Zinc citrate in lipstick to effect anti-microbial property. The drawback in using Zinc or its salts is that mostly they are emetic and cause conjunctivitis as side effect.

In an International Congress of Essential oils, fragrance and flavours November 1989) the description of use of aroma has not at all been mentioned in lipstick. The available lipsticks in the international market are used as refreshing beautifying agents only.

U.S. Pat. No. 5,665,778 describes yet another cosmetic formulation consisting of ceramides and other compounds, The composition of this patent is a totally synthetic composition.

U.S. Pat. No. 5,676,957 describes a skin external agent, said agent being an extract of the plant of genes Euonymus such as Euonymus alata. This extract according to this invention may be formulated with a cosmetically acceptable base.

Reference is made to a U.S. Pat. No. 5,858,348 wherein only a single isolate of essential oil like rose oxide has been used in synthetic lipstick and other cosmetic for refreshing feel. Such a single isolates of essential oil will not serve the desired multiple effects like mood enhancing, sensual pleasure and thought inducing state of mind.

To the knowledge of the applicants, there does not exist any lipstick with herbal colours and functional attributes, the cosmaceuticals like eye shadows and glow glitters, rouges with use of herbal colours, likewise the lipstick without colour with functional attributes for men.

The alcohol soluble matter may be concentrated at reduced pressure of 50-100 psi and a low temperature of 40-60° C. Thus, the said concentrate may be eluted with silica gel column chromatography by using non-polar solvents like—petroleum ether, hexane, cyclohexane, toluene and mixture of said non-polar and polar solvents, The polar solvents may be used like—chloroform, acetone, ethylacetate & methanol. The ratio of the non-polar and polar solvents may be 20:1 to 4:1. The concentration of the column fractions may be made at a range of reduced pressure of 80-100 psi and a temperature of 30-60° C. The colours of the concentrate may be pastel red, pale red, purplish red, rose red, cerise, ruby red, deep magenta, beet root purple, amaranth, dark purple, dark violet, deep violet, deep blue and blackish blue

These novel colours may be used with or without the aroma isolate/essential oils. Proper mixture of aroma isolates/essential oils may result in such desirable properties of mood enhancement, sensual pleasure, antidepressant and creative thoughts inducer To get these desired properties in cosmetics like lipsticks the herbal colours may be mixed with selected mixture of aroma and applied to the base material. These herbal colours may be used in other applications like eye shadow, glow glitters, rouges and skin conditioning agent.

These colours may be the mixture of naphthazarins and may be cyclic unsaturated diketones in which double bonds and keto group may be conjugated. These herbal colours may be changed to different shades by treating it with organic and inorganic acids. The intensity of these colours may be increased with organic acids and may be decreased with inorganic acids. The range of the concentration of the acids may be 0.1-10%. The colour of the herbal colourants may be changed from red to blue with organic and inorganic bases. The range of the concentration of the bases maybe 0.1-20%.

These herbal colours may have excellent lipophilic properties and very minimum hydrophilic properties. These colours may be soluble in organic solvents like—hexane, petroleum ether, benzene, diethyl ether, ethylacetate, chloroform, acetone and alcohol in the range of 30-100%. The pH of the extracted colours may be within the range of 5-6. All these characteristics of the herbal colours are very desirable for use in cosmaceutical applications. The process of the present invention can obtain various colours such as described in the tables 3 to 6.

The present invention is illustrated further by referring to the following examples. However, the present invention is not limited to these examples.

Process

Extracted the powdered material with non-polar solvents (like hexane, petroleum ether, toluene and cyclohexane) and mixtures of non-polar and polar solvents (The polar solvents are chloroform Acetone, Ethylacetate, methanol, ethanol).

The ranges of ratio of non-polar and polar solvents are 99:1 to 0:100.

The change of color by treating the color with traces of food grade acids e.g. Acetic acids less than 0.1%

The change of color with the treatment of traces of bases i.e. less than 0.1%.

Example 1

100 gm air-dried coarsely powdered root of Onosma species is sieved in 40 mesh sieve and then extracted in Soxhlet apparatus with hexane at a temperature of 50° C. for 12-18 hours which resulted in the formation of hexane soluble herbal matter. The said matter was concentrated at a reduced pressure of 70 psi and at a temperature of 35° C., resulting in the yield of 6.0 gm. as the purplish red colour (Plate NO 12 A7 of Methuen handbook of colour, 1978).

Example 2

100 gm air dried coarsely powdered stem and root in the ratio of 1:4 of Onosma species is sieved in 40 mesh sieve and then extracted in Soxhlet apparatus, with chloroform, at a temperature of 60° C. for 18-24 hours which resulted in the formation of chloroform soluble herbal matter. The said matter was concentrated at a reduced pressure of 80 psi and at the temperature of 40° C., resulting in the yield of 8.5 gm. as the beet-root purple (Plate No: 13 D8)

Example 3

100 gm air dried coarsely powder stem, root and leaf in the ratio of 1: 1: 3 of Macrotomia species is percolated at room temperature with the mixture of chloroform and hexane in the ratio of 5:95 for 4 hours (3 times). Combined all the extracts and concentrated at a pressure of 70 psi and a temperature of 50° C. Thus 3.5 gm of cerise colourant (Plate No: 12 C8) was obtained.

Example 4

100 gm air-dried coarsely powdered root of Onosma species is sieved in 40 mesh sieve and then extracted in Soxhlet apparatus with hexane at a temperature of 50° C. for 12-18 hours which resulted in the formation of hexane soluble herbal matter. The said matter was concentrated at a reduced pressure of 70 psi and at a temperature of 35° C., resulting in the yield of 6.0 gm. as the purplish red colour (Plate NO 12 A7) which gets changed to rose red after treatment with 1% formic acid.

The fractions obtained with aforesaid solvents were concentrated at the reduced pressure of 90 psi and at a temperature of 40° C., thereby giving the yield of 0.3 gm as the pastel red colour (Plate No:9 A5) which gets changed to vivid blue (Plate No: 21 A8) with the addition of the 0.1% NaOH.

Preparation of Cosmetic Compositions

The herbal colourant obtained by the process described in Examples 1 to 7 can be used according to the invention to develop various cosmetic compositions useful as lip stick, eye-liners, eye-shadows, glow-glitters and rouges. Such compositions are prepared following the general principles used in making cosmetic compositions. Specifically, the herbal colourant obtained from the plant parts is mixed with a base in appropriate proportion. The base may be liquefied first and the colourant of choice may be added and stirred. Alternatively, the colourant and the base are added, the mixture is heated, and the ingredients are stirred to obtain a homogenous mixture. To this mixture, essential oil is added together with softening agents, mood lifting agents and other additives as may be necessary for the compositions. For instance, if glow-glitters composition is to be prepared, with the basic composition, additives that provide glitter are added. The composition prepared when cooled to room temperature becomes suitable for use as a cosmetic composition.

While the above is only an outline describing the preparation of cosmetic composition, specific instances of preparing different cosmetic compositions for various applications is described in Examples 10 to 17 here below. The specific instances provided herein below are meant only to illustrate the invention and the same should not be construed to limit the scope of the invention in any manner.
